I was at Banana Beach for a couple of days last week. This was my third or fourth stay there and it was terrific as always. Tim and his folks do a great job.
As to the breakfast, you get a voucher good for either the "Banana Beach Breakfast" at no charge or US$5 toward any breakfast. The Banana Beach breakfast was scrambled eggs, a selection of fresh fruit, a banana muffin, a delicious fresh-baked cinnamon roll and juice or coffee. Basically it's a filling full breakfast except that it doesn't come with bacon or other breakfast meats. If you want to add that or something else, you pay US$2 for a side order of bacon, and the same for sausage, fry checks, potatoes and other items.
You can certainly get by fine with the free included breakfast or for a couple of bucks more get the full breakfast you want.
